UAS2D820MHD

The UAS2D820MHD is a Nichicon UAS-series radial lead aluminum electrolytic capacitor offering 82 µF capacitance at a 200 V rating. It combines a compact radial can package (φ12.5 × 25 mm) with a wide operating temperature range and elevated ripple handling to support general-purpose power and industrial designs.

Designed for applications requiring DC smoothing, decoupling and high-frequency ripple tolerance, the UAS2D820MHD delivers verified endurance and safety features in a small footprint suitable for bulk or bag packing.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 200 V rated voltage and capacitance tolerance of −20% to +20%.
• High ripple capability — Low-frequency ripple current 360 mA (120 Hz) and high-frequency ripple current 576 mA (10 kHz) for effective smoothing in switching environments.
• Wide temperature range — Operates from −40 °C to +105 °C, supporting a broad set of ambient conditions.
• Endurance — Rated life of 2000 hours at 105 °C under DC bias plus rated ripple current, with defined limits for capacitance change, tan δ and leakage current.
• Safety features — Series design includes an improved safety feature for abnormally excessive voltage and a pressure relief vent to mitigate dangerous failure modes.
• Compact radial-can package — Case diameter φ12.5 mm and length 25 mm with 5.0 mm lead spacing (±0.5 mm) for through-hole mounting and dense board layouts.
• Electrical characteristics — Maximum tan δ of 0.15 (measured at 20 °C, 120 Hz) and leakage current specified per product data (756 µA nominal for this part).
• RoHS compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Switch-mode power supplies — Bulk smoothing and output filtering where 200 V rating and strong ripple handling improve voltage stability.
• Industrial power electronics — DC link decoupling and energy buffering in control and power-conversion circuits operating across a wide temperature range.
• Instrumentation and measurement — Noise suppression and supply stabilization in precision instruments that require reliable long-term endurance.
• General-purpose electronics — Through-hole mounting for repairable or serviceable boards that need compact, high-voltage capacitance.

Unique Advantages

• 200 V rating with 82 µF capacitance: Provides substantial energy storage in a compact radial-can form factor for medium-voltage circuits.
• Elevated ripple performance: Specified ripple currents of 360 mA (120 Hz) and 576 mA (10 kHz) enable effective filtering across low and high frequency domains.
• Wide operating range: −40 °C to +105 °C operation supports demanding ambient conditions without derating the component selection.
• Proven endurance: 2000 hours at 105 °C under rated stress gives designers a clear lifecycle expectation for high-temperature applications.
• Built-in safety venting: Improved safety features for abnormal voltages and a pressure relief vent reduce risk in fault conditions.
• Compact, service-friendly package: φ12.5 × 25 mm radial can with 5 mm lead spacing for easy through-hole assembly and manual servicing.
